Hi again, just wanna to inform you that I rolled back 2004 update to 1909. I also installed older nVidia drivers. Nothing's changed. There is last option - rearrangement my room to previous state (I changed some things like I put UPS under the desk, near my feet and some minor changes of monitor placement). If that doesn't help I will give up. This will mean that my body has stopped dealing with this monitor or that it is a symptom of a disease. No idea.

    CorvusCorax In my experience IT can take over a week for the symptoms to dissipate, so perhaps give it a bit of time if you're absolutely sure you're back to the old setup and drivers. There's also a stress element - in the same way that a person allergic to pollen may develop a reaction when you produce a bunch of plastic flowers, I'm certain that our bodies can trigger headaches and migraines when working on machines that have caused you problems in the past. But it does fade with time, for me at least.

    I discovered (with an AM radio) that the switching power supplies in my UPS and monitor bricks and desk speakers were giving off serious radio frequency interference. i switched to headphones & moved things away (to another circuit) with extension cords. not a complete fix, but definitely makes a difference.

    CorvusCorax Any updates on your situation? We are on the same boat and I'm a Pole as well, so if you found any helpful specialist in Poland, please let me know.

      Dominic For now I'm back to my old monitor (Dell 2209WA), it's OK. Not great, but better. I think my problem comes from few things. Which one trigger the symptoms IDK, but I'm sure that is linked to my neck. For now I try to exercise the spine and my neck. I see some differences for better. I will let you know if something change. If you are from Poland you can write PM to me.

        CorvusCorax I feel you so much man. I also thought it was neck, or eyes, or whatever. You have to consider that all these are constants, you are used to this kind of posture/habits. But buying a new monitor and immediately getting strained, well this changes the whole equation here, it's obvious. Happened to me with S2721DGF, got nauseating migraine, which ended up making me photophobic and phonophobic... Couldn't look at any light source for 3 days straight. You should know you are not crazy, it' just something we haven't discovered yet. It's there I'm sure about that. The pixel inversion thing is interesting idea, but I got terrible inversion on my screen (BENQ GL2460), and have 6bit + FRC always on. Also got 60hz with terrible ghosting, yet, I feel just fine, can sit on this monitor for 8 hours straight. I don't know... maybe it's the brain that is used to this shitty monitor, and it's hard to adapt to something better...

        Hi Guys, i've tried 4 new monitors and i had problems with all of them. However, I can work with my old syncmaster 12 hours without any problem. I know some people improve their sight changing drivers, room light, etc but I have the suspicion that the problem it's the new monitor hard.

        Try running them on 1080p instead of 1440p. For some reason that has resolved eyestrain on several high DPI monitors, to run that at lower than native res, notable my BenQ EW3270U and EW3280U.. And it's much better than just increasing scaling. I think there's more to it than "things are bigger". Some shenanigans get disabled on some monitors when run at lower than native.

          degen Using the program Stacer in Ubuntu Linux, and going to the GNOME section, I'm able to change the hardware acceleration for text from Fast to Good to Best. Does anyone here know what exactly this does, and what setting should be best? I'm experimenting with it now.

          woww, I'm sooo happy that I found this post and this forum
          I'm from tunisia, 20 years old last summer I spent most of it working even in the curfew
          then before a month of school return I took some rest and bought a new laptop wish is Aspire 3 with I3-8130U CPU,
          4GB of RAM 2400MHz and I added other 4GB to it, 1T HDD, MX130 nvidia graphic card and a 15.6" HD (13660 x 768 px) screen. then after the new laptop I bought new glasses (crizal prevencia) that are blue and green light blocking I guess I'm not sure about that but they're supposed to be like that and they're expensive. anyway in period we were in curfew and I've been looked in my house + I'm a computer science student and computer science is life to me. so in that period I had a lot of struggling times with my head pain, nausea, dizziness and neck pain and a lottt of depression and pressure
          I didn't think of the laptop nor my glasses cuz they were new, my gf told me it's just because u're not used to be locked at home and u're spending too many hours on screens, so I tried to do not use my laptop for a day but it didn't make any deffirence (as I read above It'll take take several days to get back to normal. so yeah makes sence it doesn't work ) but I didn't know about that at that time so I just keept using it and suffering from dizziness and sleepless nights (it effected my sleep too). from that time I searched a lot and a lot about it and I found that posture can cuz all of that so I started trainning and working on it cuz I'm tall and I don't have a good posture and had a lot of pain neck. but nth worked and I literally done a lot of more things like I've done all the kind of stuff I can do. it literally screwed up my whole life, I gave up on everything and stayed like that in bed for days cuz I couldn't find any solution I did blood tests and I found nth, I did and MRI test on my head same I found nth. until someone told me that he had the same problem before with his glasses so I tested them and I tested my eyes again and found nth everything is normal. today 24/01/2021 I've been searching about my glasses types (CRIZAL PREVENCIA) and I found out that some people but only a little few of them had eye problems from it when using screens, so I said maybe that's it but I'm not sure yet.
          sometimes I go at my friends house and we play with his ps4 that is plugged with a big TV. so everytime when I go and play with him I get the strongest dizziness and nausea, so everytime I go to him I end up telling him that I feel dizzy and I go back home.
          this problem costed me a lot of damage mentally and physically, I've been living with disorders, forgetfulness and a lot of brain damage. but these days I got over that and I don't spent too much time on my laptop as before so it's better then before but still I get those feelings of nausea and dizziness
          I've been reading a lot of articals about eyes and brain and other stuff, and now I ended up in this forum
          did anybody find a solution yett?? I'm soo confused
          so it's the monitor that is causing all of this right??

          Edit:
          I checked my new laptop screen it's a led screen, and I checked my friends screen that's causing me nausea too, it's led too, then I checked my tv and my home computer that I'm fine with them they are lcd
          so I guess I have problems with led monitors

          Hi all, just want to inform you that I went back to using my new monitor Dell AW2521HF (IPS, 240Hz, 24"). It's still cause me eye strain, but not as bad as few weeks ago. The good news is, I don't have nausea and head pain. I still feel some kind of discomfort, but not as much as before.

          I'm 95% sure that my symptoms were caused by neck. For now I'm regulary excercise my neck (only 10min, 4 days a week) and do some general stretching for whole body twice a week. It's not much, but gives good results. I hope all symptoms dissapear in near future.

            CorvusCorax Do you experience any discomfort while staring at screen in off state for 2-3 minutes? I've recently discovered the reason of bad headaches (primary visual cortex area?) and some eye strain from usage of new Dell S2721QS. It has soft matte finish which differs from my previous monitor (Dell U2312HM) with heavy matte one.
            Basically, just staring at screen with no image for some time makes back of my head hurt for a couple of hours.
            I don't think that it's the more present direct reflections which affect me in this way because I use my glossy laptop (XPS 9575) without any issues (dithering is disabled).

              pl01 Hi. IDK, but I am sure that my problems are also connected to the matte finish of the screen. The problems with neck is one thing, but now I see that I can't focus on text because it blurry for me. So, end of my story it's neck problems with combination of the matte finish. In near future I will sell this monitor.

              • pl01 replied to this.

                CorvusCorax BTW Did your neck start hurting right after you bought this monitor?
                In my case, I felt some tension in my neck from the first day of owning the new monitor.
                Firstly, I thought that it was connected to going from 23" to 27" display, but now I am not so sure about it.

                  pl01 My neck problem is a compilation of few things:

                  • I bought new bike in 2020 with very demanding position (like in cyclocross) and make above 5k km on gravel roads in 2020 on it.
                  • Bad computer chair
                  • Bad position in front of the computer
                  • [deleted]

                  please check for overdrive setting of your monitor. this is a technology used for blur reducing but it will increase light strobing.

                  Many of these people not have 240Hz monitor, so i doubt they can provide the answer u looking for. I for one have been using it for 1 month now (Alienware AW2721D). I'm using 3 monitors at once (another 2 of them is 144hz & 75Hz). Cpu is ryzen 9 5900x & gpu rtx 3090 Ti evga ftw3 ultra (rip evga GPU businesses, they have issues with Nvidia).

                  Even now, 240Hz give my brain a hard time to focus. 240Fps is too smooth & fast. No matter games i played (warframe, destiny 2, sword art online alicization, all 8 yakuza, & another 100+ games), give me same experience of hard time focusing.

                  But once i lower down the Hz to 120Hz or play heavy games like cyberpunk, metro exodus enhanced edition, red dead redemption (games that lower fps to 140 & below), I'm having no issues playing normally.

                  Thus, in my case, it's the refresh rate giving me issues. So, i know this is a lot to ask with how expensive 240Hz monitor u bought, but reducing the Hz of monitor might be the only thing that can cure your issue or maybe train ur brain to at least 6 months to become familiar with it.

                  pl01 I have an ACER NP515 glossy screeen and is ok for my eyes ( till some recent updates on Win 10 )..

                  If I look at a matte screen, i instantly get aches in my eyes and terrible discomfort. Maybe cause they are too grainy?
